Almost the whole of the UK is under an amber weather warning because of strong winds from Storm Isha.
The Met Office’s Amber Wind Warning is in force across the whole of the UK except London and parts of the South East from 6:00pm on Sunday.
Wind gusts of up to 80 mph (128 km/h) are expected, posing a danger to life. The Met Office said it was very rare for the whole of the UK to be on such a state of alert.
BBC Weather reporter Matt Taylor said disruption would continue into Monday.
Two amber warnings are in place from 6:00 p.m. One stretches across central, eastern and western England and all of Wales.
The remainder includes all of Scotland, northern England and Northern Ireland.
The Republic of Ireland’s Met Éireann weather service has issued a red warning – the highest level – for winds in the north-west of the country.
The agency said Isha would bring “strong and destructive winds, especially in coastal and exposed areas”.
BBC Weather reporter Matt Taylor said “high winds” were expected across Britain later in the day.
Wind gusts of 50 to 60mph will be felt widely across the UK with gusts of 70 to 80mph around some coasts. At Capel Curig, Snowdonia, a wind gust of 90mph was recorded on Sunday afternoon.
In addition, there are yellow warnings for rain covering the whole of the UK including London, and areas in the South East are not subject to amber wind warnings.
Disruptions could continue into Monday morning rush hour.
Mr. Taylor added that Hurricane Isha is a low-pressure weather system that brought heavy snowfall to the northeastern United States last weekend and has grown as it crossed the Atlantic.
The Met Office said there was a possibility of power cuts, which could affect mobile phone signals in affected areas, while roads and bridges could be closed. Rail and bus services may face delays and cancellations.
It continued that there was a threat to life in coastal areas due to high waves and debris blown inland.
As part of wider guidance, it also warns people to minimize risks by staying away from windows when at home.
Met Office forecaster Marco Petagna said there was also the possibility of “isolated tornadoes” hitting parts of western England.
Passenger and freight services across Scotland will be suspended from 7pm on Sunday, with ScotRail saying there will also be no peak hour services on Monday morning.
Network Rail is also imposing 50mph speed restrictions across England and Wales as a safety measure, aimed at keeping trains safe from fallen trees and debris on the tracks.
It added that the restriction would “lead to fewer services with extended journey times”.
Rail companies including Avanti, LNER and Transpennine said the storm would affect their services and warned customers against traveling on Sunday.
Southeastern canceled Monday’s early morning trains before 06:00 into and out of London to allow engineers to examine the debris.
Other railroads are advising travelers to avoid traveling during the storm.
British Airways has canceled a number of flights and apologized to customers for the disruption.
British Airways said: “Like other airlines, we have had to adjust our schedules due to adverse weather conditions across the UK and Europe caused by Storm Isha.
Meanwhile, ferry companies have announced a series of cancellations. Irish Ferries said sailings between Holyhead and Dublin as well as between Pembroke and Rosslare have been cancelled.
Meanwhile, DFDS said the Dover, Calais and Dunkirk services were operating with delays, and the service between Newcastle and Amsterdam could also experience delays.
A spokesman for the Energy Networks Association, which represents UK operators, said on Friday: “Amber warnings increase the risk of damage to homes and critical infrastructure.
“Energy grid operators are preparing to handle any damage quickly and safely.”
The heaviest downpours are possible on Sunday as 30mm-50mm of rain could fall in many places – and peaks of 80mm-100mm are likely in the hills.
The Met Office said heavy rain could lead to flooding this week. As of 12am on Sunday, the Environment Agency had issued eight flood warnings, where flooding is possible in England, and 59 flood warnings, where flooding is possible.
After days of freezing temperatures and snowfall in some parts of the UK, higher temperatures are expected over the weekend – but the Met Office warns it may not feel any warmer due to high winds.
The Met Office names storms when they are likely to cause disruption or damage. The agency said it would be easier for people to follow the storm’s progress on TV, radio or social media if it had a name.
